The invention discloses a tracer flow
polymer injection profile
well logging instrument, a tracer, a tracer makeup device and a
well logging method. The
well logging instrument comprises a remote-sensing nipple equipped with a collar locator CCL, a tracer
sprayer equipped with a continuously rotating motor, and a gamma-
ray probe equipped with a near probe and a far probe. The tracer makeup device comprises a control box and a makeup box. The makeup box, which is equipped with a
lead glass screen and a
lead plate, is arranged on the control box. The bottom of the makeup box is equipped with a guide rail and a protection plate. A stirrer and a funnel are arranged above the guide rail. The stirrer is connected with a weight dropper. 4.5 to 3.5 weight shares of
solid polymer, 4.5 to 3.5 weight shares of
guar gum, and 2.5 to 1.5 weight shares of amylum are mixed with a tracer suspension to make a liquid with the concentration of 2000mg per
litter, and then the liquid together with the 0.5mCi 131Ba micro-spherical tracer to make a suspension. The tracer flow well
logging method and the
isotope tracer water-injection profile well
logging method are used for the well
logging. The tracer suspension is first evenly sprayed continuously and then is sprayed in a spotting way. The tracer suspension of the invention is even, and is provided with a low
lower limit and a high precision. Moreover, the well logging instrument of the invention is low in the cost.
